At a Pokemon's summary, in the bottom right-hand corner, there many shapes and icons. I know the red star is a notification that the Pokemon's shiny. What are the rest. Also, I got a Blaziken in GTS Negotiations, and near that place, there was some sort of a Kirby face. What's that?

And for the markings:
>They're simply markings which you can use to identify your pokemon. For example, if you have 2 of the same pokemon, you can mark one with a circle and one with a triangle to tell them apart.
